China solar cell industry
China's solar cell production to the rapid trend continues to expand in 2009 to 4382MW, estimated at more than 40% of the world. On has become the world's largest producer, and in the future will continue to expand in China solar cell industry, the author's interviews in China according to reports regularly. This paper intends to adopt in March 2010 held in Shanghai "SOLARCONChina2010" and set up a meeting and exhibition, the reader interpret the status of China solar cell industry and future development.
Solar Exhibition "SOLARCONChina2010" and set up the meeting and its "6th CSPV (ChinaSoGSiliconandPVPowerConference)" March 16, 2010 - 18 in Shanghai New International Expo Centre (SNIEC) hold. Not only will the field be seen out of the global economic crisis is the growing momentum of China's solar cell industry outlook, can read its future development.
2009 annual output of 4GW, more than 40% of global share
At the opening ceremony, Industry and Information Technology Department of Electronic Information Division, said Wang Bo, "China's solar cell production in 2009 reached 4382MW".
In 2008 more than 30 percent global share of China's solar cell production has been of concern to many people in the industry. Although the official 2009 global production has not been announced, but production in China over 4GW of view, many share the view that "more than 40% of global share."
Multi-crystalline Si production will expand
With the 2008 Si prices fell sharply in the past has been free to set foot in the multi-crystalline Si solar cell production with the disorder, has been gradually restricted. As a result, prices become stable in Si at the same time, the industry also began to have a down to earth feel.
On the other hand, taking into account the long-term growth, the Si production in China can only meet market demand in China is also about half. Therefore, the will to focus on long-term growth initiatives. Wang Bo, "the government is studying the company access to multi-crystalline Si production base, scheduled to be announced shortly."
On the production side, a number of equipment manufacturers at the show and set up the meeting and released to increase the capacity of multi-crystalline Si ingot furnace technology. Release device can be changed from its original capacity of 500kg to 800kg. Efforts in production, coupled with the orderly growth of government support for industry, Si crystal production in the future is also expected to continue to expand.
Thin-film solar cells are also steadily
China's solar cell industry, although in a previous production of crystalline solar cells, driven by rapid expansion, in fact, China's thin-film Si and CIGS thin film solar cells, the same can be said positively. Involved in thin-film Si solar cell manufacturing business for almost 60. Which is not only to their own technology based companies, but also a package of (Turn-Key) to import equipment to start business enterprises.
But in this exhibition, in addition to Zhejiang Chint Solar (Astronergy) active display and publicity, other vendors, only Baoding Tianwei Group (BaodingTianWeiGroup) and Best Solar tech (BestSolar) exhibited a few companies such as a thin-film Si solar cell panels. From manufacturers in meeting the release situation, although the thin-film Si-based manufacturing costs in general lower than about 10% crystalline, but the current conversion efficiency is low, not enough confrontation crystalline competitiveness.
About CIGS solar cells, universities, research institutes and enterprises and an important figure in setting the meeting brought together, launched a focused discussion. Although CIGS-based thin-film Si-based compared with is expected to achieve high conversion efficiency and low manufacturing costs, but acknowledged there are stability problems, currently under development.
Overall, the industry's attitude was "thin-film solar cells on the active challenge, and strive to overcome technical barriers." Although some companies did not participate in the show, but has used its own technology rather than importing expensive equipment, began producing low-cost thin-film Si solar cells. It can be said for companies with own technology, the field there is a huge business opportunity.
Attention turned to the Chinese domestic market
China's solar industry had previously been dependent on exports, but under the influence of the economic crisis, are turning to the growing Chinese domestic market. As of January 2010, China has more than 10 domestic large-scale power stations start 1MW and above, in the future there will be more projects ready for implementation.
Shanghai Jiao Tong University in China in 2020, the amount of solar power into making a bold prediction: "will greatly exceed 20GW, also is expected to reach 200G ~ 500GW".
Hitachi R & D long-lasting battery life of up to 10
Hitachi said today that it has developed a technique to enhance the lithium-ion batteries double the life of the methods for the cell cathode to improve the use of manganese materials for the battery life of up to 10 years, reducing the replacement battery brought costs.
Long-lasting lithium-ion battery is widely used, such as wind turbines can be used to store excess energy, but also can enhance the portable electronic product life cycle.
Before, Apple has released a way to make MacBook and MacBook Pro repeated charge life of up to 5 years.
